The Event Horizon Telescope's polarized view of Sagittarius A*. The lines mark the orientation of polarization related to the magnetic field around the black hole's shadow.EHT Collaboration A new ...

All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the ...

A new model that posits the same physical process is responsible for magnetic field and the rotation patterns, contradicting previous theories that the sun’s magnetic field originates deep inside its ...

Our Sun is far from a smooth, white ball in the sky. Twisting and looping magnetic field lines rise from its surface like hair, causing dark, transient patches on the surface called sunspots wherever ...

The Earth’s magnetic field, a silent guardian against harmful solar radiation, has been behaving strangely in recent years. This has sparked many questions and concerns about the implications of such ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. Nov 28, 2025, 07:59am EST Map of the strength of the Earth's ...

Earth’s magnetic field nearly collapsed long ago. What saved it explains why life survived and why the planet remains ...

Stars are born in a cosmic tug-of-war. The interplay between gravity, turbulence, and magnetic fields (B-fields) weaves ...

A new photo of the supermassive black hole at our galaxy's core looks different from those before. Scientists released the photo, captured by telescopes from around the globe, on Wednesday. The image ...

A new model contradicts previous theories that the sun's magnetic field originates deep inside its interior. Deep origin theories could not explain rotation patterns of the sun's gas near its surface ...

This illustration lays a depiction of the sun's magnetic fields over an image captured by NASA’s Solar Dynamics Observatory. The complex overlay of lines can teach scientists about the ways the sun's ...
